With the pressure to constantly look camera-ready, the best accessory to have in Hollywood might just be flawless skin. Aesthetician Matty Solomon is the secret weapon behind many a celeb’s complexion, tending to the mugs of some of the most high-wattage stars. Eva Mendes, Sandra Bullock, Kyra Sedgwick and others visit her West Third Street spa faithfully every six weeks for a rejuvenating Collagen Facial, $135. But you don’t have to live in Los Angeles to take advantage of Matty’s magic. The Matty European Skincare and Cosmetics line also has a loyal following of superstar clients who stock their vanities with Matty’s Purely C Serum, $65, a potent antioxidant that is reputed to repair visible signs of aging and sun damage. And many Hollywood makeup artists keep a supply of Vitality Day Cream, $60, on hand, to help keep celebrity skin picture perfect during awards season.
